`Hudson and State of New Jersey, have in-A vented certain new and `useful, Improvein is a specification.

e invention relates to improvements 1n tures, structure and combinations o parts hereinafter described, and particularly pointed out in the'clairns.'y

I` present my `invention herein as emb odied in a stove of the character used in or boiling candy, the stove proper consistlngof a verticalV cylindrical body having a top adapted t receive a candy kettle.' @ne object of my invention is to provide a highly efficient gas-burner `to be located within thestove and possessing a gas-chainber and an air-chamber, the latter surrounding conical of greater-'diameter than themselves in the top of said airchamber, whereby air, under ressure,v may be supplied to the air-chainer and issue around the nipples atthe points at which ignitiontakes place.

. A further object of the invention is to provide ythe gas-pipe leading to theburner `with a self-closing valve `and withy inecl1ay nism for opening said valve, said mechanism 35' extending above the stove in position to be `engaged b the handle-of the candy kettle, `whereby tie kettle may, whenon the stove,

be-ut-ili'zed as the means for keeping said f valve in its open position;` Upon t-h'e removal of the kettle from the stove the valve in the gas supply-pipe will automatically thus thev attendant will not have tire attention to the kettle and its contents.

The invention will be fully understood from the ldetailed description hereinafter presented, reference being had to the accompanying drawings,.in which:

of the gas-burner, the section being on the .dottedlincB-S of Fig. 1, land Fig. 4 is an enlarged detached sectional view showing of the air chamber con,-

portion of the top to receive .the upper end taining an orifice of said nipple. i

ln the drawings, designates .a customary form of stove used in candy factories,l and 11 a usual forni. of kettle thereon, said kettle having handles 12 projecting laterally from its opposite sides. f

The novel features of my invention reside in the gas-burner and its connections with which the stove is -ecpiippedfl `The gas burner is designated by theinunier'azl 14, and" it is supplied with gas from a supply pipe 15 and with air under pressure from anair supply pipe 16, the*y latter being led to the `from any suitable blower or Source The gasburner comprises a body portion 1T within which is formed a gas-chamber 18 connected with the supply-pipe 15. The top 19 of the gas chamber 18is formed with a series of upwardly tapering conical n ip.` ples 20 through which the gas inay escape from said chamber and at the outlets from which ignition takes place. Upon` the body' 17 of the burner and extending entirely over `one of,v the nipples of the gasburner and a the top of the same is secured a frame 21. j

which has `a concave upper surface, a vertical encompassing {iange 22 and ahorizo'ntal flange 23 extending outwardly from the ktegrally The top imV together by means of bolts passing through apertures. in the fianges 23, 24; and between said top frame 21 and ythe top 19 of the body 17 is formed an air chamber 25, which is coi extensive with the top of the body 17 and surrounds all of the nipples 20, which project upwardly through said air chamber and into rorifices 26 formed in the frame 21, said orifices being of greater diameter than the nipples and permitting air to escape from around the nipples while the Vgas escapes through the nipples, the air and gas mixing at the points of combustion. ber 25 is in communication with a tubular section 27 extending through the body pol"- tion 17 of the burner' and projecting slightly below the same where it is in communication with.the supply pipe 16 for'air under pressure The air chamber 25 thus receives its air from the supply pipe 16 through thev tubular section 27 which opens directly into the middle of said chamber 25.

The burner is thus formed of'two parts secured together and forming a gas-cham ber 18 and an air chamber 25, these two chambers being independent of each other with the air chamber superposed over the gas chamber and surrounding the nipples, at the upper ends of `which ignition takes place.

The gas-supply pipe 15 leads into the gasehamber 18 and has interposed in it a verltical pipe section 28 supporting at its upper end a bracket 29 and within its vlower end affording a seat 30 fora valve 31, the latter being provided for controlling the fiow of gas through the pipe 15 and carried on a rod 32 which extends upwardly above the pipe section 28 and is pivotally connected, as at 33,. to a lever arm 34, which is. pivoted to the upper end of the bracket 29. The lever arm 34 is of angular form, as shownin Fig. 2, and when moved laterally and downwardly toward the left, looking at Fig. 2, it will depress the valve 31 from its seat and thereby open the passage for gas through the pipe 15. I provide below'the valve 31 a coiled spring 35 which acts to normally hold the valve 31 closed against its seat 30. The valve 31 will thus automatically .close whenever the lever arm 34 is released to permit it to close, and said valve may only be opened by pressure applied to it sufficient to overcome the force ot' the spring35. The leven arm 34 extends above the `stove `10 and in a 60. l "they kettlell is'placed onthe be turned or twisted thereon position to be engaged by' a handle 12 of the kettle 171', so that the kettle may be utilized as the means'for holding the valve 31 in an open position; upon the removal of the kettle' from. the stove the valve 31 willithereby closeLl When stove it may to move the handle 12L against the lever arm34 andv czf use be Vreleased vto automatically r said arm to turn outwardly and downwardly toward the left, looking at Fig. 2, to depress The air cham- 'l I the rod 32 and yopen the valve 31, the weight ofthe kettle being sufficient to resist the force of the spring 35 tending to restore the valve and lever arm to their initial positions. When the kettle 11 is lifted from the stove 10, the lever arm 34 will thereby be released and the spring 35 will at once close the valve 31. y

The burner 14 formed of the body-portion 17 and top frame or cap 21 is very advantageous in its results, in the facility with which it may be manufactured, inspected and cleaned and in its being practically indestructible. The nipples 2O are cast integrally with the body 17 and are conical or of twyer'construction. The vnipples 20 are in circular concentric rows, the outer row being somewhat more elevated than the inner row; and the top frame or cap 21 is in one integral. casting adapted to fit down upon the body 17 with the nipples entering the orifices 26 formed therein to receive them. The frame or cap 21 presents a concave upper surface, and this feature is of importance in that it concentrates the heat be low the kettle 11, The convex lower sury face of the frame or cap 21 tends to an efficientdistribution ofthe air within the air- Yhamber 25. The conical formation of the nipples 20 also aids in the proper distribution of the air in and its escape from 'the airchamber 25, the inclined sides of said ni ples preventing dead air spaces in said c amber and promoting the upward passage of the air to the outlet oriiices 26.

What I claim as my invention and desire to secure by Letters Patent, is:

'A gas burner comprising a body portion forming within it a gas-cham er, supply pipe for gas leading into said chamer, a top-frame removably securedv on said body portion and. having orifices therein and forming below its top whichcontains said orifices and between its sides and the top of said body portion an air-chamber, means for ,the delivery of air to said air chamber, and a series of nipples extending upwardly from saidgas-chamber through vsaid air-chamber and into said orifices, sald top frame having 'a concave upper surface and a convex lower surface, and said air delivery means being located to direct the air against said convex surface at itscenter; substantially asset forth. f
